Two men in their late thirties were on the way home from fishing when, on impulse, they decided to pull over on Rio Dam and throw their lines for one last time. They were both about to cast the lines when they noticed an oval-shaped craft flying low over the lake and approaching them. The craft was rusty to brownish purple in color and had a dull "matte to purple finish." The object had about five portholes that emitted a green "fluorescent light" from inside. From the front of the object, two purple pinkish beams of light swept forward and down to Rio Lake. The beams appeared to have "substance" inside them, apparently sucking up water from the river. The craft reached to about 100 feet away from the witnesses then they saw an entity inside the object. The entity had a leathery, wrinkled-looking face and large pointed ears. Its skin was of a light brownish color, it had a round mouth, round eyes, and its face was flattened against the rectangular porthole of the object. It also had two hands thrown up against the window near its head. It moved its mouth and appeared to be exclaiming in great surprise upon seeing that he was being watched. Immediately the object accelerated to a high speed and continued its course, quickly disappearing from sight at very low altitude over the dam.
